How Painful Is Cataract Surgery?

Cataract surgery involves removing the eye’s cloudy natural lens and replacing it with an artificial intraocular lens (IOL). This common procedure uses local anesthesia, which effectively prevents pain during the operation. The goal of modern surgery is to restore vision while ensuring patient comfort. Therefore, the procedure itself is widely considered painless.

What You Feel During the Procedure

The eye is numbed using local anesthesia, most commonly with medicated eye drops applied directly to the surface of the eye, or occasionally a mild injection near the eye. This localized approach eliminates the sensation of pain while allowing the patient to remain awake and cooperative during the short, 10 to 20-minute surgery. Patients are often also given a light sedative intravenously, which helps them relax and minimizes anxiety.

While pain is blocked, patients should be prepared to experience other sensations that are distinct from pain. The most common sensations include a feeling of pressure or a gentle tugging as the surgeon manipulates the eye tissue and instruments. Because the surgical microscope uses a bright light, patients will typically see a kaleidoscope of colors, like blues, yellows, or reds, or simply a bright, indistinct light. Some patients may also notice the sensation of coolness from the sterile fluids used to irrigate the eye during the procedure.

Expected Discomfort Right After Surgery

Once the local anesthetic begins to wear off in the hours immediately following the surgery, it is normal to experience a range of temporary discomforts. These feelings are generally not described as acute surgical pain, but rather as irritation from the eye’s surface healing. Many people report a gritty or sandy sensation, similar to having an eyelash stuck in the eye, or mild itchiness.

Other common temporary symptoms include increased tearing, slight redness, or a dull pressure or ache behind the eye. This immediate post-operative irritation occurs as the small surgical incisions begin to close and the eye adjusts to the manipulation. These expected feelings of irritation typically peak on the day of the procedure and then subside significantly within the first 24 to 48 hours.

Strategies for Managing Recovery Discomfort

Managing the expected post-operative discomfort relies on a clear, multi-faceted strategy provided by the surgeon. A standard regimen includes prescribed anti-inflammatory and antibiotic eye drops, which are instrumental in minimizing swelling and preventing infection. Consistent and correct application of these drops is the most important step in controlling irritation and promoting a smooth recovery.

For managing general aches or headaches, most surgeons approve the use of common over-the-counter pain relievers, such as acetaminophen. Non-pharmacological measures can also provide relief from the mild irritation. Applying a cool compress or a clean, damp cloth to the outside of the protective eye shield can be soothing. Resting the eyes by avoiding intense visual activities like reading or screen time in the immediate hours after surgery helps reduce strain and irritation.

Recognizing Pain That Requires Medical Attention

While mild discomfort is normal, it is important for patients to distinguish this from symptoms that may indicate a complication. Any severe, sharp, or throbbing pain that is not alleviated by the prescribed or approved pain medication warrants an immediate call to the surgeon’s office. This kind of intense pain is rare but can be a sign of increased intraocular pressure or an infection.

Other warning signs that require urgent medical attention include a sudden decrease in vision, flashes of light, or a shower of new floaters. Excessive eye redness or swelling that worsens after the first day, or any discharge from the eye, should also be reported immediately. Prompt communication with the surgical team about these severe symptoms is necessary to ensure any potential complication is addressed quickly.
